Peter Eckersley, may his memory be a blessing

I'm devastated to report that Peter Eckersley (@pde), one of the original founders of Let's Encrypt, died earlier this evening at CPMC Davies Hospital in San Francisco.

Peter was the leader of EFF's contributions to Let's Encrypt and ACME over the course of several years during which these technologies turned from a wild idea into an important part of Internet infrastructure. He also took a lot of initiative in coalescing the EFF, Mozilla, and University of Michigan teams into a single team and a single project. He later served on the initial board of directors of the Internet Security Research Group.

He really made his mark helping encrypt today's web.

It's funny. If someone had asked me, seven years ago, "what is the key principle of teaching Physics," I would never have said "mystery." Now it would be at least a top-3 idea.

The only way I know how to teach is this:
1) Students summarize their understanding.
2) We poke the universe with some experiment or activity.
3) Students admit that this makes no sense.
4) We name the mystery.
5) We use logic, more experiments, graphs, etc. to solve the mystery.
6) Students summarize their (new) understanding four ways, naming this their "current model."
7) We poke the universe again, and the cycle of confusion-->named mystery-->model begins again.

Principles of UI, A Thread:
1. natural mapping
2. visibility of system state
3. discoverability
4. constraints and affordances
5. habits and spatial memory
6. locus of attention
7. no modes
8. fast feedback
9. do not cause harm to a user's data or through inaction allow user data to come to harm
10. prefer undo to confirmation boxes. For actions that can't be undone, force a "cooling off" period of at least 30 seconds.
11. measure using Fitt's, Hick's, GOMS, etc. but always test with real users.

IF YOU PROGRAM A "NO" BUTTON TO SAY "MAYBE LATER" YOU HAVE FAILED AT BOTH INTERFACE DESIGN AND BASIC CONSENT

Working on an extra-chromatic version of NGC 3132 that utilizes all of the available filters from the near-infrared of NIRCam to the mid-infrared of MIRI. Needs much work, but I can see a worthy composite underneath all the bad.

"Andy Saunders has an obsession. It's Project Apollo, one of the defining events in our species' history.

But he's also got a deep frustration. And that's the pictures that record those remarkable space missions in the late 1960s and early 1970s.
[...]
The result is a gloriously sumptuous new book called Apollo Remastered. Four hundred pictures that detail humanity's first foray to another world."
